 data storage. This is the standard implementation of a bag.
 <p>
 A <code>Bag</code> stores each object in the collection together with a
 count of occurrences. Extra methods on the interface allow multiple copies
 of an object to be added or removed at once. It is important to read the
 interface javadoc carefully as several methods violate the
